CIRCULAR-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 451,713, datedMay 5, 1891.

Application filed July 31, 1890. Serial No. 360,5Al. (No model.)

To all whom it may concern:

Be it known that I, ADAM KAY, ofthe village of Georgetown, in the county ot'fHalton, in the Province of Ontario, Canada, have invented a certain new and useful Improvement in Circular-Knitting Machines, of which the following is a specification.

The object of the invention is to design simple mechanism by which the cam-cylinder will be automatically reversed for heel and toe work when the machine is in operation; and it consists, essentially, of two rings revolubly fitted onto the cam-cylinder, one above and one below the driving-pinion, each ring having a rack on its face to engage with the said driving-pinion, which consequently propels the two rings in opposite directions, a movable bolt, fitted into the cam cylinder, being engaged by automatically operating mechanism, which causes the bolt to move so as to lock the cam-cylinder to either one or other of the rings, according to the direction it is desired that the cam-cylinder should revolve, substantially as hereinafter more particularly explained, and then definitely claimed.

Figure l is an outside view of a part of a knitting-machine, showing the mechanism for automatically operating the bolt. Fig. 2 is an enlarged perspective sectional detail of the reversing-gate and parts connected therewith. Fig. 3 is a sectional elevation of part of a knitting-machine, showing the location of my driving-rings. Fig. 4 is an enlarged detail of a portion of the cam-cylinder and rings, showing the location of the bolt. Fig. 5 is an enlarged detail showing the sliding ate. a In the drawings, A represents the cam-cylinder, provided with a shoulder a,which shoulder forms a bearing for the ring B, said ring being revolubly fitted onto the cylinder A and having teeth formed on its bottom face to engage with the teeth of the driving-pinion 0.

I) is a ring similar to the ring B, also revolubly fitted onto the cam cylinder A, the bearing for said ring D being a ring D, fitted into a ring I. The teeth of the ring D are formed on its top surface so as to engage with the bottom side of the driving-pinion O.

A -slotted passage-way E is made through each of the rings B and D, as indicatedin Fig. 4.'

. F is a bolt slidingly fitted into a recess a in the enlarged portion of the cylinder A in such a manner that by lifting it it will enter the slot E in the ring B, and thus lock the said ring B to the cam-cylinder A; or by pressing the said bolt F down it will enter the slotted passage-way E in the ring D and lock the said ring D to the cylinder A. A metal strip f holds the bolt F in place.

As before stated, owing to the connection between the driving-pinion O and the rings B and D, the said rings revolve in opposite directions. Consequently, when the cylinder A is locked to the ring B the said cylinder will revolve in one direction, while when it is connected to the ring D it will revolve in the opposite direction, the driving-pinion C revolving always in the same direction. WVith a view of effecting this reversed action automatically,I fix to the bolt F a projecting pin G and provide a slanting movable gate II in the outer stationary ring I. The normal position of the gate H is inside of a recess (shown in Fig. 5) made in the ring I. In order to reverse the cam-cylinder, the gate II is pushed out, as shown in Fig. 5, so that the pin G on the bolt F, which revolves with the cylinder A, shall come in contact with the said gate, and as the gate H is in a slanting position the pin G, when it comes in contact with it,

is pressed upon, so as to push it, with its bolt F, either up or down, according to which side of the gate thepin G comes in contact with. For instance, if the pin G strikes the bottom side of the gate II, its bolt F will be pushed down into the slotted passage-way E, made in the ring D, or, should the cylinder A be revolved in the opposite direction, the pin G will come in contact with the top side of the gate H, and thus force the bolt F up into the passage-wayE made in the ring B. In order 5 to throw this gate 11 into or out of action at the time required, I provide the following simple mechanism: A shank J is fixed to the gate II and projects through the outer stationary ring I. A slot is made in the end of Loo the shank J, through which a slide K passes. A diagonal slot L is made in the slide K,

through which a pin M passes, the said pin being fixed to the shank J. The slide K is suitably held in the vertical slot made in the outer stationary ring I, in such a manner that it may be easily moved up and down. Owing to the manner in which the slide K is connected to the shank J, the vertical movement of the slide K causesthe gate to move in or out. WVith aview of accomplishing this movetion I use, for Working the other parts of the machine automatically, at sprocket-Wheel Q, which derives rotary movement from the driving-spindle. Around this sprocket-wheel I place a sprocket-chain R, with raised links,

What I claim as my invention is- 1. The cylinder A, driving-pinion C, and the rings B and D, fitted loosely around the cylinder on each side of said driving-pinion, to which the said rings are geared, in combination with a movable bolt F, arranged to connect the cylinderA to either one of the rings B or D, substantially as specified.

2. The cylinder A, driving-pinion O, and the rings B and D, fitted loosely around the cylinder on each side of said driving-pinion, to which the said rings are geared, a movable bolt F being arranged to connect the cylinder A to either one of the rings B or D, in combination with the gate II and automaticallyoperating mechanism designed to act on said gate, substantially as specified.

3. The cylinder A, driving-pinion G, and the rings B and D, fitted loosely around the cylinder on each side of said driving-pinion, to which the said rings are geared, a movable bolt F being arranged to connect the cylinder A to either one of the rings B or D, in combination with the gate H, connected to the shank J, and the slide K, having a diagonal slot L in it, through which a pin M passes, the lever N, revolving sprocket-wheel Q, and chain R, substantially as specified.
